Abstract
A study was undertaken to determine the effectiveness of different limestone formations for use as agricultural limestone.Samples were obtained from nine limestone formations representing three geological systems.These samples were obtained from the face of the formation exposed at different quarries.The limestones were crushed and sieved in the laboratory.Chemical composition and physical properties were determined.
Data from this investigation indicate that the addition of liming materials to a strongly acid Sharpsburg soil does not significantly increase the percent calcium and yield of alfalfa.The change in pH of the soil depended more on particle size than on type (dolomitic or amorphous or crystalline calcitic) of limestone.However, there appeared to be real differences in effectiveness of the different types of liming materials as reflected by their physical and chemical properties.
